This is a bit of a general question.
I am creating a tournament scheduler in Excel and I was wondering if I could do something a bit more advanced than just spreadsheet sharing for teams to update their scores.
My thinking is this: Create a macro with specific username and password for each team and they can then only update their own scores, and have the opposing team be able to approve the scores to validate them. I don't think that coding this would be a problem but my issue here is that I do not know where I can upload this for everybody in the tournament can have access to it as we do not have a shared file server. How can I have the shared spreadsheet available to everybody freely?
